PATENT FQF F ECE SHUTTLE Applicatio n filed December 5, 1925. Serial-No.323,819.

g This invention relates to a shuttle or weft carrying device for loomsand particularly to a 100111 of thetype shown and described in myapplication for loom, executed and filed on even date herewith, SerialNo. 323,818.

This shuttle is akin to another application for shuttle, executed andfiled by me on even date herewith, Serial No; 323,817, and also intendedforFuse with the loom above mentioned. i I

E'The object of the invention herein is to provide a shuttle that willreceive a loop of weft thread and after it has been passed through thewarp shed and returned to its initial position, will be operated tosever the loop heldbyoit andto receive anew loop for asuccessiveoperation. A

Another'objecti of the invention is to providemeans to be automaticallyoperated by the loom to perform-the above function.

According to the invention, the shuttle is conventionally. shaped andprovided with arotatable member having a. plurality' oi hooks forsuccessively severing the loop of woven weft and receiving a new loop ofweft thread to be woven,- and' ratchet means adapted to be operated bythe loom for rotat ing the said hook member at the precise moment whenone loop is to be disengaged, and anew loop received by the hook member.Y a The invention also contemplates the employmentfof' step-up gears forproviding .a higher speed of rotation for the hook memberthan for theratchet means. a I The drawing illustratesanembodiment of the inventionand the views therein areas Figure 1 is a side view of the shuttle,Figure 2 is a top plan view thereof,

Figure 3 is a longitudinal sectional view taken on the line 33 of Figure2 and looking in the direction of the arrows,

F gu e 4'is' a cross-sectional vlew o fl l QHr fFigure 2, a A

' T. Figure 51s a similar view on theline 5 -'5 of Figure 4; and p p iFigure dis a like view on the line 66 of Figure 2. 1

' In configuration the shuttle'is' substantially the same astl'ie-conventional shuttle and coinprises a body 11' having the usualpointed steel ends 12 with the fibre plate 13 therebe tween. .The'body11 is usually constructed of wood or some very light material and isrecessed as shown at 14 in Figure 3; This recess is'prov'lded with ametallic bearing member 16 which is flush with the 'top of the shuttleand such bearing member has a cutout portion-or recess 17 therein inhorizontal alignment with the recess 18'extending trans-,

Versely through the-body 11 of the shuttle and shown in Figures 1 and 4so that there is formed 'a transverse channel extending enti relythrough said shuttle." Thef-bearing member has an e lip 19' which fitsagainst the outen vertical wall of the-recess 14 and has a plate part 21I whose outer end fits againstthe inner vertical wall offthe recess 14.I

The space immediately below the overhanging. lip '19 is occupied by aplate 22 which has overhanging k a knife edge 23 onthe leftjhan'diside-ot the same and by a rotatable hook member 24 mountedon a;shaft 26which extendsinto a recess 27 in said bearing and is provided insaid recess with a pinion 28 which 'meshes I with another pinion 29insaid recess and secured' to a shaft 31 which extends longi-j tudinallyand is provided on that part which extends in the, reces's'32 above theplate 21 witha ratchet wheel 33.

"As illustrated inFi'gure 5, thfpinions 28 and 29 are of diflierentdiameters and their ratio is 2to 1 so that a single rotation of theshaft 31' will rotaterthe shaft 26 and the rotatable hook member 24twice.-; The side ofthe body member vl1 is grooved, as shown at 34 'inFigures 1 and 2',- while that portion of the bodylyingbeyond the recess18 and toward'the end of the shuttle is out back a considerabledistance, as shown at'36 in Figures land 2.. This is for the purpose ofallowing weft thread tobe' drawn into the recesses 17 and 18 whereit'can be engaged by one of the hooks 37 onthe hook member" 24. vExtending transversely across the .ohanne'l formed by. the recesses 17and 18 is a groove 38 so positioned that thetip'of each onthe loom willautomatically rotate the ratchet wheel; 33 50" as to draw tli'etlirea'dover tli'ee'd' ge of the knife 23, thus severing it and at the same timethe succeeding hook will receive a new loop of thread to be woven intothe fabric. i s

'A more comprehensive and better understanding. of the mechanism of theloommentioned: in the foregoing'pending; application willtendto clarifythe'ioperatioir of the mechan isr nherein. t g

i The pinions 28 and 29 have been provided because? in: a directconnection,- the azction of pawl upon the ratchet wheel would hardly begreat enough to providea quarterrevolutio r Ora- .90 movementof the hookmember.

It will, however, be readily seen that when the book 1 member is"rotated 90 with the thread lying in. the lowermost hook 3 7,. thatthread. will bev engagedwith the knife 23 and severed, while a newthread which is placed acrosst-he groove 38. will. be picked up and heldbythe succeeding hook. v V
